Blind Rivet GESIPA PolyGrip® 3.2x8.0 mm Aluminum/Stainless Steel, pack of 100

Blind Rivet GESIPA PolyGrip® 3.2x8.0 mm Aluminum/Stainless Steel, pack of 100 is a blind fastening component designed for reliable joining of thin sheet materials when access is restricted to one side. The rivet features an aluminum body combined with a stainless steel mandrel, providing a balance of lightness and corrosion resistance. Supplied in a pack of 100, these blind rivets are intended for use with compatible blind-rivet tools in assembly, repair and maintenance operations across metalwork, composites and selected plastics.

Advantages

The aluminum body reduces weight and lowers the risk of galvanic corrosion on many base materials, while the stainless steel mandrel ensures consistent setting and improved shear strength compared with all-aluminum constructions. These rivets are engineered to deliver uniform blind-side formation and a clean visible finish, offering vibration resistance and predictable remaining mandrel break-off. Supplied in a bulk pack of 100, they simplify stock management and support repeated fastening tasks.

Suitable for

• Fastening thin sheet metal panels and enclosures
• Joining composite panels and sandwich constructions
• Repair and maintenance work where only one-side access is available
• Applications requiring neat visible heads and vibration-resistant joints

Key specifications

• Rivet type: blind (solid blind rivet designed for one-sided access)
• Body material: aluminum
• Mandrel material: stainless steel
• Rivet diameter: 3.2 mm
• Grip length / set length: 8.0 mm
• Pack quantity: 100 pieces
• Intended materials: thin metals, certain plastics and composite materials

How to use

Select an appropriate blind-rivet tool compatible with a 3.2 mm mandrel. Drill a clearance hole equal to the rivet diameter, insert the rivet through the materials to be joined until the rivet head sits flush or as required, and operate the rivet tool until the mandrel breaks off at its designed break point. After setting, confirm the blind-side deformation is secure and that the visible head is correctly seated on the material surface. Dispose of used mandrels according to local waste regulations.

Recommendations

Use these rivets with tools calibrated for stainless-steel mandrels to ensure consistent break-off and full setting. Pre-test on sample panels when joining dissimilar materials to verify grip range and corrosion compatibility. Store in a dry environment to preserve component condition.
